New subject: d3d9: Set IDirect3DDevice9Impl_GetVertexShader return value to NULL on error

23 Dec 2008

Hi,

Please write a test for this. This behavior differs from function to
function unfortunately. Some functions do not set the value to NULL, and
some apps depend on this.

I think dlls/d3d9/tests/shader.c is a good place to put this test.

 NULL on error

 When IWineD3DDevice_GetVertexShader fails, set *ppShader to NULL.

 This fixes "Black & White 2" here: it used to crash right when first
 level intro video ended, before seeing the level. With this patch I can
 play a bit (though there are some graphical glitches remaining, mouse
 it not so
 smooth...)
